  In the joinery as described above, since the resin member that closes the opening is screwed to the back plate member, the attachment of the resin member is complicated. Also, since the resin member that covers the opening provided in the bag and the back plate member that is provided with the heating foam material that presses the resin member, the heating foam material is foamed and made of resin. Before reaching this member, the resin member may be heated by the heat of the bag and ignite.

  The present invention has been made in view of such problems, and the object of the present invention is to make a resin product that can be easily attached, covers the opening, and can be more reliably separated from a metal part when heated. It is providing the fitting provided with the member of.

  In order to achieve this object, a joinery of the present invention is provided with a synthetic resin resin member that is provided in a metal hollow member having a hollow portion and covers a communication hole that communicates the hollow portion with the outside from the outside. The resin member is inserted from the outside and held by the hollow member; a cover portion that covers the communication hole; and the insertion hold portion and the cover portion are connected, and the insertion hold A connecting portion that is more fragile than the portion, and a heating foam material is provided in the insertion holding portion or the covering portion.

  According to such a joinery, the synthetic resin resin member covering the communication hole is connected to the insertion holding portion inserted from the outside and held by the hollow member and the cover portion covering the communication hole by the connecting portion. The communication hole can be covered with the cover simply by inserting the insertion holding member into the communication hole from the outside. Also, since the heating foam material is provided in either the insertion holding part and the cover part connected by the weak connection part, when the resin member is heated, the connection part melts and the insertion holding part The cover part is separated, and the foamed heated foam material can be filled in the hollow member. For this reason, it is providing the fitting provided with the resin member which can be easily attached, covers a communicating hole, and can be more reliably separated from a metal part when heated.

In this joinery, it is preferable that the insertion holding part has an engaging part that is held by being engaged with the hollow member, and the heating foam is provided in the insertion holding part.

And the heating foam material may be provided on the inner surface facing portion.

  According to such a joinery, the heating foam material provided in the inner surface facing portion foams toward the inner surface of the hollow portion, and starts to spread around when reaching the inner surface of the hollow portion. For this reason, it is possible to make it fill in the hollow part. In addition, since the insertion holding portion also has a hole side surface portion having a surface facing the communication hole side, the foamed heating material that starts to expand is restricted by the hole side surface portion and spreads to the communication hole side. Become. For this reason, it is possible to press the cover part covering the communication hole in the direction away from the facing part, break the connecting part earlier, and separate the cover part from the insertion holding part.

In such a joinery, it is desirable that a portion of the portion of the insertion holding portion that faces the cover portion is connected to the cover portion by the connecting portion.
According to such a joinery, a part of the portion of the insertion holding part that faces the cover part and the cover part are connected by the connecting part. That is, the entire portion of the insertion holding portion that faces the cover portion is not connected to the cover portion. For this reason, since the cross-sectional area of a connection part is smaller than the cross-sectional area of an insertion holding part, it is possible to make a connection part weaker than an insertion holding part.

  In this joinery, the hollow member is a saddle member that constitutes a shoji included in the joinery, the communication hole is a small opening of the saddle member, and the resin member is a cap that covers the small opening. desirable.

  According to such a joinery, it is possible to easily cover the forehead by simply inserting a cap made of synthetic resin into the saddle material constituting the shoji, and when heated by a fire or the like, the cap is covered. It is possible to more reliably separate the portion from the brazing material and to close the forehead with the foamed heated foam material.

  This joinery includes a frame body that surrounds the outer periphery of the shoji, the cap is heated to break the connecting portion, and is pressed against the foamed heated foam material, and the cover portion is foamed with the frame body. It is desirable to be sandwiched and held between the heated foam materials.

  According to such a joinery, the cover portion of the resin member that is heated and broken at the fragile connecting portion is pressed in a direction away from the insertion holding portion that is held in the hollow portion by the foamed heating foam material. . And since the cover part pressed away from the insertion holding part is held between the frame surrounding the outer periphery of the shoji and the foamed heating foam, the cover part separated from the insertion holding part is a hollow part. It is possible to prevent falling off.

Hereinafter, a fitting according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1 and FIG. 2, the joinery of the present embodiment is a sliding window joinery 1 provided with an inner shoji 2 and an outer shoji 3.

  In the following description, when the joinery 1 attached to a building or the like is viewed from the indoor side, the vertical direction is the vertical direction, the horizontal direction is the horizontal direction, and the depth direction is the indoor / outdoor direction. Shown as direction. Even if it is each site | part of the joinery 1 and each member which comprises the joinery 1 is a single-piece | unit state, in the direction used as the up-down direction, the left-right direction, a prospective direction, etc. in the state in which the joinery 1 was attached The direction is specified and explained.

  The joinery 1 of the present embodiment is provided with an aluminum frame 4 as a metal framed in a rectangular shape, and is movably provided along the frame 4. The joinery 1 is formed by the frame 4 and communicates the interior and the outdoors. The inner shoji 2 and the outer shoji 3 capable of closing the opening 4a are provided.

  The inner shoji 2 and the outer shoji 3 are composed of two upper and lower ridges 21 and 31, door toe ridges 22 and 32, and a summon made of a composite material in which an extruded member made of aluminum and an extruded member made of synthetic resin are combined. It has the housings 20 and 30 in which the laminated rods 23 and 33 are joined in a rectangular shape, and the multilayer glass 5 in which the peripheral ends are accommodated in the housings 20 and 30. The inner shoji 2 and the outer shoji 3 are mounted on the rail 41a provided on the lower frame member 41 of the frame 4 surrounding the outer periphery thereof, and the door cart 6 provided on the lower side rails 21 and 31 is placed on the lower frame. Guided by rails 41a and 42a provided on the material 41 and the upper frame material 42, the opening 4a moves so as to be opened and closed.

  In a state where the opening 4a is closed by the inner and outer shojis 2 and 3, the upper and lower reeds 21 and 31 and the door-end reeds 22 and 32 are provided on the rails 41a and 42a provided on the frame body 4 and the vertical frame. Although it is engaged with the fin-shaped portion 4b, the summing rods 23 and 33 are engaged with the frame 4 only at the upper and lower ends, and are merely pulled and locked together by the crescent lock 4c. Compared with the upper and lower horizontal reeds 21 and 31 and the door-end reeds 22 and 32, they are easily deformed. For this reason, the summoning cage 23 of the inner shoji 2 has an aluminum reinforcing portion 232 that forms a hollow portion 23a penetrating in the longitudinal direction on the indoor side of the aluminum cage main body 231 located on the outdoor side. It is provided integrally with the upper and lower horizontal fences 21 and 31 and the door-end fences 22 and 32 so as to protrude indoors.

  The reinforcing portion 232 is formed shorter than the rod main body portion 231, and the rod main body portion 231 is hollow above and below the small opening 232 a serving as a communication hole that communicates the inside and outside of the hollow portion 23 a at the upper end of the reinforcing portion 232. It protrudes downward from a small opening 232a as a communication hole that communicates the inside and outside of the portion 23a. Here, the bag main body 231 in which the reinforcing part 232 is integrally provided in the summoning bar 23 of the inner shoji 2 corresponds to a hollow member.

  An end cap 7 as a resin member made of a synthetic resin that is inserted from the outside and covers the forehead 232a is provided in the forehead 232a that is the upper and lower ends of the reinforcing part 232 of the summoning ward 23 of the inner shoji 2. Yes. Here, the small opening 232a of the reinforcing portion 232 corresponds to a communication hole (opening) for communicating the hollow portion 23a with the outside. In the present embodiment, a synthetic resin holding cover material 8 is provided that covers the outer peripheral portion of the summoning bowl 23 of the inner shoji 2 from the indoor side and holds the peripheral edge of the multi-layer glass 5 together with the bowl main body 231. Yes.

  The end caps 7 that cover the upper and lower fore ends 232a of the reinforcing portion 232 are the same member. In the following description, the end cap 7 that covers the upper edge 232a is taken as an example, and the end cap 7 is attached to the upper edge 232a in the vertical direction, the left-right direction, the prospective direction, and the like. Identify and explain.

  As shown in FIGS. 3 and 4, the end cap 7 is inserted into the small opening 232a from the outside of the hollow portion 23a and held by the reinforcing portion 232, and a cover 75 that covers the small opening 232a, The insertion holding part 70 and the cover part 75 are connected to each other, and the connection part 79 is weaker than the insertion holding part 70 and the cover part 75.

  The cover 75 includes a cover main body 76 that closes the small mouth 232 a, an edge 77 that slightly hangs downward from the left and right edges and the inner and outer edges of the cover main body 76, and an outdoor side of the cover main body 76. It has a collar contact portion 78 that extends upward from the edge and contacts the surface 231a on the indoor side of the collar body portion 231.

  The outer surface 78a of the heel contact portion 78 is projected outwardly and is engaged with a locking hole (not shown) provided in the heel body portion 231 when the end cap 7 is attached to the reinforcing portion 232. A locking piece 78b to be stopped is provided. The locking piece 78b has a tapered shape such that the thickness in the prospective direction decreases downward.

  In the state of the end cap 7 alone, the heel contact portion 78 is slightly curved outward on the upper end side. For this reason, when the end cap 7 is attached to the reinforcing portion 232, the heel contact portion 78 is pushed back by elasticity and is brought into contact with the indoor side surface of the heel body portion 231. That is, the hook contact portion 78 presses the indoor side surface 231a of the bag main body portion 231, and the locking piece 78b is locked to the locking hole and is attached to the reinforcing portion 232.

  The insertion holding part 70 includes a pair of opposing plate parts 71 that are opposed to each other in the left-right direction, a lower end connecting part 72 that connects lower ends of the pair of opposing plate parts 71, and a pair of opposing plate parts 71 and lower ends. In order to increase the rigidity of the insertion holding portion 70, the indoor plate portion 73 that connects the indoor edge of the connecting portion 72 and the reinforcing rib 74 that connects the lower end connecting portion 72 and the indoor plate portion 73 are provided. In the present embodiment, when the end cap 7 is attached to the reinforcing portion 232, the lower end connecting portion 72 has a surface facing the fore edge 232a, so that it corresponds to a hole side surface portion, and the indoor plate portion 73 corresponds to the hollow portion 23a. Since it faces the inner surface, it corresponds to the inner surface facing portion.

  A taper 71a having a width that narrows downward is provided at the lower end of the pair of opposing plate portions 71, and is inserted downward into the lower end of the indoor side surface of the indoor plate portion 73. A taper 73a is provided so that the expected width of the holding portion 70 is narrowed.

  Further, when the insertion holding portion 70 is inserted into the reinforcing portion 232, the insertion holding portion 70 is engaged with the inner surface of the indoor plate portion 73 by engaging the inner surface of the reinforcing portion 232. A front engaging portion 73b to be press-fitted is provided. The front engaging portion 73b has an upper edge that coincides with the upper edge of the indoor plate portion 73, and a taper 73c at the lower end portion thereof such that the thickness of the front engaging portion 73b in the prospective direction decreases downward. Is provided.

  The pair of opposing plate portions 71 are protruded to the opposite side to the opposite side, and are inserted by engaging the inner surface of the reinforcing portion 232 when the insertion holding portion 70 is inserted into the reinforcing portion 232. A side engaging portion 71 b is provided in which the holding portion 70 is press-fitted into the reinforcing portion 232. The side engagement portion 71b is provided at the same position in the height direction as the front engagement portion 73b, and a taper 71c is formed at the lower end portion so that the thickness of the side engagement portion 71b in the prospective direction is reduced downward. Is provided.

The pair of opposed plate portions 71 extends upward from the indoor plate portion 73, and the upper end portion thereof is connected to the lower surface of the cover portion 75 to form a connecting portion 79. That is, the connecting portion 79 that connects the insertion holding portion 70 and the covering portion 75 is a simple plate-like portion that is connected to a part of the portion that faces the covering portion 75 in the insertion holding portion 70. The cross-sectional area is smaller than the cross-sectional area in the horizontal cross section of the portion facing 75. For this reason, the connecting portion 79 is more fragile than the insertion holding portion 70.
In the end cap 7 of the present embodiment, thermally expandable graphite 9 as a heating foam material is attached to the outdoor surface 73 d of the indoor plate portion 73 of the insertion holding portion 70.

  As shown in FIG. 5, when the end cap 7 is attached to the reinforcing portion 232 from above, the insertion holding portion 70 connected by the connecting portion 79 is press-fitted and held under the cover portion 75 that closes the small opening 232a. Thus, a space S (FIG. 3) surrounded by the pair of opposed plate portions 71, the lower end connecting portion 72, the indoor plate portion 73, and the indoor side surface 231 a of the bag main body portion 231 is formed. The thermally expandable graphite 9 is arranged in the space S so as to face the indoor-side surface 231a of the bag main body 231.

  The joinery 1 of the present embodiment is exposed to a fire flame whose outside is the source of fire, and when the outside of the summoning bowl 23 of the inner shoji 2 is heated, the reinforcing part 232 from the aluminum main body part 231 is heated. Heat is transmitted to. At this time, the thermally expandable graphite 9 is expanded and filled in the space S before the end cap 7 made of synthetic resin is melted by the transmitted heat. Further, when the thermally expandable graphite 9 expands, the thermally expandable graphite 9 expands from the space S and fills the hollow portion 23a of the reinforcing portion 232 and presses the cover portion 75 from below.

  Due to the pressing of the thermally expandable graphite 9, the connecting portion 79 heated and melted from the insertion holding portion 70 and the cover portion 75 is broken as shown in FIG. The cover 75 is separated from the mating bar 23 or at the end cap 7 on the lower end side. Thereby, since the cover part 75 isolate | separated from the summon bowl 23 becomes difficult to be heated, ignition can be prevented. At this time, when there is a possibility that the separated cover portion 75 is dropped and placed on a metal member different from the summon bowl 23, it is pressed from below by the foamed thermally expandable graphite 9. In this case, the separated cover 75 may be sandwiched and held between the foamed thermally expandable graphite 9 and the frame body 4. On the other hand, as shown in FIGS. 7 and 8, the thermally expandable graphite 9 starts to expand from the hollow portion 23 a of the reinforcing portion 232, and the insertion holding portion 70 is covered with the expanded thermally expandable graphite 9. Can be prevented.

  According to the joinery 1 of the present embodiment, the synthetic resin end cap 7 that covers the small mouth 232a of the summoning cage 23 of the inner shoji 2 is inserted from the outside of the hollow portion 23a and the reinforcing portion 232 of the summoning cage 23. Since the insertion holding part 70 and the cover part 75 covering the forehead 232a are connected by the connecting part 79, the cover part 75 can cover the forehead 232a simply by inserting the insertion holding part 70 from the outside. is there.

  In addition, since the heat-expandable graphite 9 is provided in the insertion holding portion 70 connected to the cover portion 75 by the fragile connecting portion 79, the connecting portion 79 is melted when the end cap 7 is heated. The insertion holding part 70 and the cover part 75 are separated, and the reinforcing part 232 can be filled with the expanded thermally expandable graphite 9. In the connecting portion 79 of this embodiment, only a part of the portion of the insertion holding portion 70 facing the cover portion 75, that is, the end portions of the pair of opposing plate portions 71 are connected by the cover portion 75 and the connecting portion 79. . In other words, the entire portion of the insertion holding unit 70 that faces the cover 75 is not connected to the cover 75. For this reason, it is possible to make the connecting portion 79 more fragile than the insertion holding portion 70 by making the cross-sectional area in the horizontal direction of the connecting portion 79 smaller than the cross-sectional area in the horizontal direction of the insertion holding portion 70. .

  Since the separated cover 75 is removed from the reinforcing portion 232, the cover 75 is not heated and the ignition from the cover 75 can be suppressed. For this reason, it provides a joinery 1 having an end cap 7 that is easily attached, covers the forehead 232a, and has a cover portion 75 that is more reliably separable from the summon bowl 23 when heated, and that is difficult to ignite. There is.

  Further, the insertion holding portion 70 is securely held by the side engagement portion 71 b and the front engagement portion 73 b that engage with the reinforcing portion 232, and connects the cover portion 75 connected by the insertion holding portion 70 and the connecting portion 79. The part 79 can be easily separated from the reinforcing part 232 by being broken by melting or the like. At this time, the hook contact part 78 integrated with the cover part 75 and separated from the insertion holding part 70 is released from a state in which the inner surface of the bag main body part 231 is pressed by elasticity. The stop piece 78b is easily removed from the locking hole, and a force acts on the cover portion 75 integral with the flange contact portion 78 in a direction away from the fore edge 232a. For this reason, it is possible to remove the heel contact portion 78 and the cover portion 75 from the reinforcing portion 232 more reliably.

  Further, even if the cover 75 is separated, the insertion holding part 70 held in the hollow part 23a of the reinforcing part 232 is provided with the heat-expandable graphite 9, so that it foams after the cover 75 is separated. It is possible to block the forehead 232a with the thermally expandable graphite 9.

  Further, the thermally expandable graphite 9 provided in the indoor plate portion 73 foams toward the inner surface of the hollow portion 23a, and starts to spread around the inner surface of the hollow portion 23a. For this reason, it is possible to fill the hollow portion 23a more reliably. Further, since the insertion holding part 70 also has a lower end connecting part 72 having a surface facing the fore edge 232a, the thermally expansive graphite 9 that has started to expand by being foamed is restricted by the lower end connecting part 72 and is thus adjusted to the fore edge 232a. Will spread to the side. For this reason, it is possible to remove the cover part 75 from the insertion holding part 70 by pressing the cover part 75 covering the small opening 232a in the direction away from the indoor plate part 73 and breaking the connecting part 79 earlier.

  In the above embodiment, the communication hole provided in the hollow member made of aluminum and connecting the hollow portion and the outside is the small opening 232a of the reinforcing portion 232. It may be an opening provided with a synthetic resin member such as a handle.

In the above embodiment, the metal hollow member is made of aluminum. However, the present invention is not limited to this, and may be made of iron or stainless steel, for example.
Moreover, in the said embodiment, although the weak connection part 79 was demonstrated as a structure which connects only the edge part of a pair of opposing board part 71 with the cover part 75, a weak connection part has melting | fusing point lower than the insertion holding | maintenance part 70. Any structure that melts faster than the insertion holding unit 70 may be used, such as being formed of a member, or having a thinner connecting portion than the insertion holding unit 70.

  In the said embodiment, although the example in which the thermally expansible graphite 9 was provided in the indoor board part 73 facing the inner surface of the hollow part 23a was demonstrated, not only this but the thermally expansible graphite 9 faces the small edge 232a side. You may be provided in the surface by the side of the fore edge 232a of the lower end connection part 72 which has a surface. In this case, it is possible to press the cover part 75 covering the small opening 232a in a direction away from the lower end connecting part 72 by the expansion of the thermally expandable graphite 9. For this reason, it is possible to break the connecting part 79 earlier and remove the cover part 75 from the insertion holding part 70.

  Moreover, in the said embodiment, although the example in which the thermal expansion graphite 9 was provided in the insertion holding | maintenance part 70 side was demonstrated, the thermal expansion graphite 9 is provided in the surface facing the insertion holding | maintenance part 70 of the cover part 75. FIG. It does not matter.

  In the said embodiment, although the edge part cap 7 as a resin member demonstrated the example provided in the summoning cage | basket 23 in the shingles 2 of the fitting 1 for sliding windows, it is not restricted to this, For example, mutually Any member having a hollow portion, such as a butting rod in a four-storied joinery having two butting shojis to be butted and two sleeve shojis, may be used. In addition, the hollow member to which the end cap 7 is attached is the summing bowl 23 made of a composite material of an aluminum member and a synthetic resin member, but is not limited thereto, and has a hollow portion and a hollow portion. Any metal member having a communication hole communicating with the outside may be used.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
